PORTABLE PUDDING-MACHINE.

To all whom it may concern:

Be it known that we, CHARLES HERMAN OVERLY and OWEN ALoNzo THoMrsoN, citizens of the United States, residing at In dependence, in the county of Montgomery and State of Kansas, have invented certain new and useful Improvements in Portable Pulling-liachines, of which the following is a specification.

The present invention relates to improvements in portable pulling machines to be used for the purpose of pulling rods or tubes from bored wells.

The primary object of the invention is to improve machines of this type in several particulars and especially for providing a simple but effective carriage or truck by means of which the pulling machine may be transported from well to well; to provide improved means for raising the rods or tubes when it is necessary to connect more rods or tubes for the purpose of placing them in the well, by providing a mechanical lift to release the elevator from under the knuckle of the tube or rod, and the invention is further designed to provide certain other improvements as will be apparent from the following.

The invention consists, in certain novel combinations and arrangements of parts as hereinafter described and claimed.

In the accompanying drawings is illustrated one complete example of the physical embodiment of the invention constructed according to the best mode so far devised for the practical application of the principles of the invention.

showing a locking device by means of which the carriage or truck is connected with the mast of the machine while being transported. Fig. 6 is a view of a complimentary member fixed to the mast and adapted to interlock with a duplicate member like that shown in Fig. 5. Fig. 7 is a transverse vertical sectional view showing the members in Figs. 5 and 6 interlocked. Fig. 8 is a side elevation showing the mast secured on the truck or carriage and adapted to be transported. Fig. 9 is a bottom plan view of Fig. 8. Fig. 10 is a transverse sectional view on line 1010, but showing the vehicle in upright position.

In the preferred embodiment of our invention the mast is comprised of the two side arms 11 which are connected by the cross bars 2, 3, l, 5, and at their bottoms are secured to the beams 6. At the upper end of the mast the usual wheel or pulley 7 is journaled, and when the mast is in working position the guy ropes 88 are extended from the upper end of the mast to the which is journaled in bearings in the two upright posts 11-11 which are fixed at-the lower end of the mast to the arms 11 and the beams 6. In connection with the reel 9 a pair of brake drums 1212 are employed, and additional reels 13-13 are provided between these two drums over which the power rope 1 1 may be wound. The central reel 9 is for the pull rope'15 which is wound upon the reel and extends up over the pulley 7, and by means of its hook 16 is adapted to engage the bail or eye 17 of the elevator 18 which. is shownin Fig. 1,'as

This elevator 18- comprises a flat plate 20 formed with trunnions 21-21 over which the eyes 2222 of the bail 17 are passed, and the plate 20 is pro-- 25', and each of these bands is connected to a crank shaft as 2627, located at each side of the beams 6, and supported in brackets 28 which are bolted to the beams. The two shafts are adapted to move in unison, and are actuated. by means of the brake lever 29 which is fixed on the shaft 26. A lever arm 30 on the shaft 27 is connected to the lever by means of a link 31 and a fixed arm 39., the latter on the lever 29 and the former pivotally connected between the arm 30 and the arm 32.

The winding reel and brake drums are integral or fixed to each other, and revolve with the shaft 10. The shaft 10 is journaled in movable bearings, and for this purpose the journal blocks 33 are provided (see Fig.

The ournal block 33 is vertically slidable between the walls of the guide slot 3% of a bracket 35 which is bolted to the mast. There are two of these brackets 35, one bolted to each of the posts 1l-11, and the shaft 10 is suspended by means of its journal blocks 33 between these brackets 35. The journal blocks are supported in the brackets by means of springs 36 which are interposed between the under side of the block, and a lug 37 projecting upwardly from the bottom wall of the slot 34:.

Referring to Fig. 3, it will be seen that when the lever 29 is turned by manual power downwardly to the dotted position, the brake band 25 will not only be tightened on the brake drum 12, but the entire winding device including the reels and drums, is borne downwardly, the supporting journal blocks 33 sliding in the slotted brackets 35. By this movement of the winding device, a mechanical lift is imparted to the machine. This mechanical lift is especially desirable and useful when it is desired to release an elevator from a rod or tube to allow the rod or tube to descend into the well. For instance, assuming that the elevator is placed under the knuckle of a rod as in Fi 4; for the purpose of holding the rod and connect ing more rods to be placed in the well, after such additional rods are connected up they are held by the elevator which rests upon the top of the well casing, and in order to disengage and free the elevator from the knuckle, it is necessary to lift this weight a slight distance to release the elevators. This lifting is accomplished by a continuation of the lever movement which applies the brakes to the drums, and it will be seen that the reels are under the control of the operator while this hoisting movement is going on. The use of this auxiliary lifting device obviates the necessity for manually holding the brake drums to give this lift, which is known as the kick-off It will be understood, of course, that horse power applied to the line or rope 14L turns the reel and winds the rope 15 to raise the rods or tubes to a sufficient height so that an additional elevator 18 may be placed under one of the knuckles for securing the rods, and in order that the withdrawn section may be detached from the tubing or rods.

."Vhen lowering rods or tubes into a well, turn the reel. forward, with the left hand, for the purpose of taking slack out of the haulline; then grasp brake lever :29 with right hand locking the reel. Then continued pressure on lever 29 brings reel. down thereby releasing elevator which will then allow rods to be lowered by lessening pressure on brake lever 29. {in additional section of tubing or red may be applied to the knuckle 24c, and the kick-off device is again brought into operation as described. In this manner one of the most hazardous and tedious portions of the work of operating the tubes or ropes is rendered safe and simple.

In addition to the above meritorious leatures of the invention, the machine is provided with a specially fashioned truck or carriage, by means of which it may be transported from place to place, and readily detached in order that the mast may be erect ed, and as easily assembled, when it is desired to transport the mast to another locality. For this purpose a wheeled carriage comprising the traction wheels i-O l-.O are supported upon the axle d1 which. has a built-up bolster i2, tongue 43, brae arms iellat connecting the axle to the tongue, and cross bar connecting the arms iflc. By means of the rods 4t6l6 which are hooked at 47, the truck is detachably connected to the rear, by engagement of the hooks 47 with eye-bolt 4:8 secured in the side arms of the mast.

F or locking the mast and truck securely together for transportation, the cross-arm or beam 3 between the side arms l1 is of special construction. in Fig. 6, this arm is shown as a cylindrical metal bar which is attached by its flanges L9 and bolts 50 to the arms 1--1 of the mast. At each end of the bar an open groove or recess 51 is formed which extends radially, at an angle to the vertical from the center of the bar. The ends of this bar 3 are adapted to rest in complementary curved seats 52 provided with the brackets 5353, one at each end of the bolster 4-2, and fixed at the upper or ge thereof. Each bracket 53 has the inclined face 5% on the lug 55, to guide the ends of the bar 3 to proper position, and the rods 46 are. each provided with a bent end 56 which is passed through a perforation 57 in the bracket 53. A. flat spring 53 may be employed to hold the bent end 56 within the perforation 57. In Fig. 7 the relationship of these parts is clearly disclosed, and it will be seen that the bent end 56 forms a trunnion upon which the bar 3 may turn, and when-the bar is turned so that the slot 51 is in vertical position, it will be apparent that the bar 3 may be lifted from its seat 52; In this manner the mast will be lifted from its truck or carriage.

For further securing the parts together,

the ends of the brace bars 4:4: are slotted at 59, to pass over the eye-bolts 6O projecting from the cross bar 4, and the hooks 61 are passed through these eye-bolts to lock the parts together. At the forward end of the truck suitable means is provided for securing the end of the tongue to the cross bar 5, and the draft gear or rigging may be attached at 63, to draw the truck over the ground.

7 By the utilization of the carriage or truck, the mast may be transported from place to place, and may be set up in position with facility and rapidity and the simple attaching devices by means of which the truck and mast are connected together may be readily disengaged, so that the carriage may be freed from the mast, and the mast hoisted into working position. This detachment of the carriage from the mast obviates the necessity of hoisting the mast to position with the carriage attached thereto, and when it is understood that the carriage frequently weighs over six hundred pounds, it will be seen that the detachment of the parts provides a meritorious feature in a machine of this character.

In Fig. 2, the mast is illustrated in a vertical position, but it will be understood that it may be tilted as desired, the drawings simply showing the vertical position for convenience of illustration.

From the above description taken in connection with the drawings it is apparent that an improved machine has been provided which fulfils the objects and purposes of the invention.
